Assertion :As...

Question

Assertion :As temperature increases, heat of reaction also increase for exothermic as well as endothermic reactions. Reason: $Δ H_{r e a c t i o n}$ varies according to the relation:
$\frac{Δ H_{2} - Δ H_{1}}{T_{2} - T_{1}} = Δ C_{P}$

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

The correct option is D Assertion is incorrect but Reason is correct
By Kirchoff's equation,
$\frac{△ H_{2} - △ H_{1}}{T_{2} - T_{1}} = △ C_{p}$
So, the variations of heat of reaction with temperature can be easily observed by above equation for exothermic and endothermic reactions.
